The parseAlgoliaHitSnippet function lets you parse the highlighted parts of an Algolia hit’s snippet.
If you’re using autocomplete-js, all Algolia utilities are available directly in the package with the right user agents and the virtual DOM layer. You don’t need to import the preset separately.

​
Installation

First, you need to install the preset. 
npm install @algolia/autocomplete-preset-algolia
Then import it in your project:
JavaScript
import { parseAlgoliaHitSnippet } from "@algolia/autocomplete-preset-algolia";
If you don’t use a package manager, you can use the HTML script element:
HTML
<script
  src="https://cdn.jsdelivr.net/npm/@algolia/autocomplete-preset-algolia@1.19.4/dist/umd/index.production.js"
  integrity="hqqZsgytphUhmmnnfNd/A5wjXf0y4hifZNUTpRvy0wM="
  crossorigin="anonymous"
></script>
<script>
  const { parseAlgoliaHitSnippet } = window["@algolia/autocomplete-preset-algolia"];
</script>

​
Examples

​
With a single string

JavaScript
import { parseAlgoliaHitSnippet } from "@algolia/autocomplete-preset-algolia";

// An Algolia hit for query "the"
const hit = {
  name: "The Legend of Zelda: Breath of the Wild",
  _snippetResult: {
    name: {
      value:
        "__aa-highlight__The__/aa-highlight__ Legend of Zelda: Breath of __aa-highlight__the__/aa-highlight__ Wild",
    },
  },
};
const snippetedParts = parseAlgoliaHitSnippet({
  hit,
  attribute: "name",
});

/*
 * [
 *  { value: 'The', isHighlighted: true },
 *  { value: ' Legend of Zelda: Breath of ', isHighlighted: false },
 *  { value: 'the', isHighlighted: true },
 *  { value: ' Wild', isHighlighted: false },
 * ]
 */

​
With nested attributes

JavaScript
import { parseAlgoliaHitSnippet } from "@algolia/autocomplete-preset-algolia";

// An Algolia hit for query "cam"
const hit = {
  hierarchicalCategories: {
    lvl1: "Cameras & Camcoders",
  },
  _snippetResult: {
    hierarchicalCategories: {
      lvl1: {
        value:
          "__aa-highlight__Cam__/aa-highlight__eras & __aa-highlight__Cam__/aa-highlight__coders",
      },
    },
  },
};
const snippetedParts = parseAlgoliaHitSnippet({
  hit,
  attribute: ["hierarchicalCategories", "lvl1"],
});

/*
 * [
 *  { value: 'Cam', isHighlighted: true },
 *  { value: 'eras & ', isHighlighted: false },
 *  { value: 'Cam', isHighlighted: true },
